“The fact is you are still young. You were 17, nearly 18 at the time; you are now just over 19. I do take into account the sentencing guidelines for sentencing children and young people. That guideline refers to people who are under 18. You are not in that category but it is well recognised that achieving the milestone of 18 is not a cliff edge and that maturity is not something that happens on a single day... I am conscious of your immaturity at the time and your borderline intelligence and I bear in mind what is set out in the psychologist’s and psychiatric reports all of which I have read in great detail. Bearing in mind what I have read I apply a reduction of two years for that reason.”
“21. In our judgment, the applicable principles are clear. Those who are under the age of 18 when they offend have long been treated by Parliament, and by the courts, differently from those who are adults. That is because of a recognition that, in general, children are less culpable, and less morally responsible for their acts than adults. They require a different approach to sentencing and are not to be treated as if they were just cut-down versions of adult offenders... Section 59(1) of the Sentencing Code requires every court, when sentencing or dealing with an offender who was under the age of 18 at the time of the offending, to follow the Children guideline except in the rare case when the court considers it would be contrary to the interests of justice to do so. Paragraphs 6.1 to 6.3 of that guideline are relevant in such circumstances, and we are unable to see any justification in logic or principle for the submission that those paragraphs should only be followed where the offender has only recently attained adulthood... “ Later, at [32], the Court went on to set out a number of points of guidance, including at (iii) and (iv): “(iii) The court must take as its starting point the sentence which it considers was likely to have been imposed if the child offender had been sentenced shortly after the offence.... (iv) The starting point taken in accordance with (iii) above will not necessarily be the end point. Subsequent events may enable the court to be sure that the culpability of the child offender was higher, or lower, than would likely have been apparent at the time of the offending. They may show that an offence was not, as it might have seemed at the time, an isolated lapse by a child, but rather a part of a continuing course of conduct. The passage of time may enable the court to be sure that the harm caused by the offending was greater than would likely have been apparent at that time. Because the court is sentencing an adult it must have regard to the purposes of sentencing set out in section 57 of the Sentencing Code. In each case, the issue for the court to resolve will be whether there is good reason to impose on the adult a sentence more severe than he would have been likely to have received if he had been sentenced soon after the offence as a child.”
“6.45 Only if the court is satisfied that the offence crosses the custody threshold, and that no other sentence is appropriate, the court may, as a preliminary consideration, consult the equivalent adult guideline in order to decide upon the appropriate length of the sentence. 6.46 When considering the relevant adult guideline, the court may feel it appropriate to apply a sentence broadly within the region of half to two thirds of the adult sentence for those aged 15 – 17 and allow a greater reduction for those aged under 15. This is only a rough guide and must not be applied mechanistically. In most cases when considering the appropriate reduction from the adult sentence the emotional and developmental age and maturity of the child or young person is of at least equal importance as their chronological age. This reduction should be applied before any reduction for a plea of guilty.”
